Therefore, GCD of numbers 345, 385, 434 is 1

Given Input Data is 345, 385, 434

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 345 is 3 x 5 x 23

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 434 is 2 x 7 x 31

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(345, 385) = 26565

GCD(345, 385) = ( 345 x 385 ) / 26565

GCD(345, 385) = 132825 / 26565

GCD(345, 385) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 434

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(5, 434) = 2170

GCD(5, 434) = ( 5 x 434 ) / 2170

GCD(5, 434) = 2170 / 2170

GCD(5, 434) = 1

GCD of 345, 385, 434 is 1
